Each of the Yeastar S-Series Appliances can terminate between 20 and 100 SIP Trunk service providers with no change to system hardware or software. However, these Appliances are also able to take Yeastar’s range of plug-in modules so that you can use legacy line types in conjunction with (or even instead of), SIP Trunks. This might be useful when you have unreliable broadband and want a back-up service in case of broadband failure. Or you may need a new phone system, but the broadband in your area is just not good enough for VoIP [yet!]. It’s also useful if you have numbers on analogue or ISDN lines that can’t be ported to VoIP. These modules make it easy to create a ‘hybrid’ PBX to make communications flexible and ultra-reliable.
Each of the S-Series Appliances use the same on-board modules:
S2 Module: two FXS ‘extension’ ports allowing connection of two analogue telephone devices such as; desk phones, DECT cordless phones, fax’ machines and credit-card terminals – to trunk line services.
O2 Module: two FXO ‘central office’ ports terminating two analogue telephone trunk lines from the local PSTN Exchange (e.g. BT).
SO Module: one FXS ‘extension’, and one FXO ‘central office’ port to connect an analogue telephone device, and an analogue line.
B2 Module: two basic rate ISDN2e ports to support connections to one or two NTE boxes, providing two or four ISDN channels (2 or 4 trunk lines), with support of Caller ID and Direct Dial Numbers.
GSM Module: one SIM card can be slotted into this module and an antenna fitted to the Yeastar IP-PBX to support calls to and from the GSM mobile phone network. Call routing plans can be configured in the management of the PBX to use this module as the primary connection route when calls are placed to mobile numbers (to take advantage of provider’s call plans).
3G Module: as for the GSM module, but for the 3G mobile phone network.
4G LTE Module: this module will support 3G/4G mobile calls and data. It will support end-to-end VoIP from a mobile device (e.g. a smart-phone running Linkus VoIP app’), through mobile data network to extensions on the company LAN.
EX30 Expansion Board: can be installed in the S100 or S300 Appliances – to provide an RJ45 interface to a 30 channel Primary Rate ISDN30e, with support of Caller ID and Direct Dial Numbers.
EX08 Expansion Board: is installed into S100 or S300 Appliances to mount up to four on-board modules on each EX08.
D30 Module: When a D30 is added to an S100 PBX, its max. capacity is raised from 100 extensions to 200 extensions, and the number of concurrent calls raised from 30 to 60. When a D30 is added to an S300 PBX, its capacity is raised from 300 extensions to 400 extensions, and the number of concurrent calls raised from 60 to 90. A second D30 may be added to the S300 to push this up to 500 extensions and 120 concurrent calls.
This modular approach across Yeastar’s S-Series IP-PBX range allows you to be confident that any type of connection can be set up to enable you to take advantage of current and future services available in your area, and competitive call-plan tariffs available to your business.
